    Factor the bottom (x + 1) (x - 3)

    now the fraction looks like (x - 3) / ((x + 1) (x - 3))

    the (x-3) 's cancel out leaving 1 / (x + 1) or D

    Simplifying

    (2x2 + - 3x + 1) (x + - 2)

    Reorder the terms:

    (1 + - 3x + 2x2) (x + - 2)

    Reorder the terms:

    (1 + - 3x + 2x2) (-2 + x)

    Multiply (1 + - 3x + 2x2) * (-2 + x)

    (1 (-2 + x) + - 3x * (-2 + x) + 2x2 * (-2 + x))

    ((-2 * 1 + x * 1) + - 3x * (-2 + x) + 2x2 * (-2 + x))

    ((-2 + 1x) + - 3x * (-2 + x) + 2x2 * (-2 + x))

    (-2 + 1x + (-2 * - 3x + x * - 3x) + 2x2 * (-2 + x))

    (-2 + 1x + (6x + - 3x2) + 2x2 * (-2 + x))

    (-2 + 1x + 6x + - 3x2 + (-2 * 2x2 + x * 2x2))

    (-2 + 1x + 6x + - 3x2 + (-4x2 + 2x3))

    Combine like terms: 1x + 6x = 7x

    (-2 + 7x + - 3x2 + - 4x2 + 2x3)

    Combine like terms: - 3x2 + - 4x2 = - 7x2

    (-2 + 7x + - 7x2 + 2x3)
